Rheostat
Product Code : SCL-CL-11867
Rheostat (SKU SCL-CL-11867) is a high-power 10 Ω variable resistor for extra-low and low-voltage circuits, used to set and limit current in physics and electrical practicals. Its impact-resistant housing carries built-in grounding terminals and 4 mm safety sockets. It serves school, college and polytechnic laboratories. Science Lab Supplies manufactures this unit at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, supplying schools, colleges, tender contractors and distributors without a middleman.

Applications and Experiments for the Rheostat
Connected in series, the resistor varies the current through a circuit; wired as a potential divider, it gives an adjustable voltage. With 5.7 A continuous rating it can also act as a load for power supplies, covering electricity practicals from Class 10 to undergraduate and diploma level.
- Class 10 and Class 12 physics: taking current and voltage readings to verify Ohm's law.
- Drawing V–I characteristics of resistors and lamps.
- Controlling current in meter bridge and potentiometer experiments.
- B.Sc., polytechnic and basic electrical engineering labs: loading and testing low-voltage supplies.
At high power the resistance element heats up, and the 600 V rating calls for care: use it under supervision, keep the grounding terminals connected and switch off before rewiring.
Standard Scope of Supply
The unit is supplied as a single rheostat as described above, in its impact-resistant housing with the 4 mm safety sockets and grounding terminals. Connecting leads, meters or a power supply are separate items that can be listed on the quotation.
Packing, MOQ and Lead Time
Quotations are prepared for one unit or a full laboratory quantity, and each sets out packing, delivery time and price for the number you request. Meters, leads and power supplies can be combined in the same request when you are building an electricity and magnetism lab kit for schools.

Frequently Asked Questions
What current can this 10 ohm rheostat carry?
Up to 5.7 A continuously and 8.0 A for 15 minutes, with permissible power of 320 W continuous or 640 W for 15 minutes.
How is it connected in a circuit?
Through 4 mm safety sockets, which accept standard safety leads. Built-in grounding terminals allow the housing to be earthed.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The resistor is produced in its own Ambala factory at Saha, and buyers deal directly with the maker for pricing and supply.
How accurate is the resistance value?
The nominal 10 Ω value is held within ±10%, which suits current control and loading in teaching circuits.
